This was low coolant for me once. It only has to be down a little bit to trigger that fault.

Iíve seen low battery trigger that fault too.

Yep low coolant. Man it doesn't take much to trigger that switch. It was low just by a little.

This is the AMP meter reading with my whole home running on it.
That includes a standup freezer, a chest freezer, a 4 ton AC unit, and a refrigerator, and all the lights and other equipment in my home on.
This can't be right? How can I check this?

If you have a friend who is an electrician or HVAC tech, borrow a clamp-on ammeter.

Each leg shows 23 amps, with my neighbors clamp meter. Where do I start looking to troubleshoot this?

@Zephyr7 Any luck finding that digital manual?

My amp meter on the gen set shows no amperage, htz and voltage work fine but the amp meter isn't. I got my neighbors clamp meter and it reads that each leg has 23 amps flowing through it with my house running. How do I fix the amp meter on the gen set? Where/what would be a good place to start looking to correct it?

You probably need to loop the output lead(s) through the CT a second time. Youíre half low, showing about 10 amps where you should see about 20. Looping the wire through the CT a second time will double the reading. Iíll check the manual for 120/240 configuration and see if it agrees.

Ok, I checked. The manual doesnít show a double loop, but it does show two in-phase windings passing through each CT. I suspect you only have one of the two windings passing through each CT which is why youíre reading half low.

Iíll check if I have an electronic manual for your set the pic is from my paper copy.

I have three metal hoops (I'm guessing CTs) at the top of the alternator. One leg is looped around what I'm guessing is the first CT and the next leg is looped through the second CT, the third CT has nothing through it.

You notice the meter does not really have any markings for the low end of its scale. It might just be that the load you have applied is just barely enough to start the meter up out of its dead band.
